Subject [jira] (MNG-4223) Resolve expressions in POM artifact coordinates
Date Fri, 07 Mar 2014 22:43:01 GMT


Jörg Hohwiller commented on MNG-4223:

There is great news for this issue:
Please note that the plugin will move out of sandbox in the future so try mojo instead of
sandbox if the link stopped working:

Simply check-out and install this plugin. Then add this to your toplevel POMs build-section:

I hope that the plugin will move out of sandbox and be released soon.

If you have any feedback please let us know (ideally on MOJOs dev mailing list).

> We need to resolve artifact coordinates in the POM, including project coordinate, dependencies,
plugins, reports, etc. but NOT plugin configuration sections. These coordinates need to be
resolved prior to plugins like GPG being executed, and prior to install/deploy steps, to ensure
that signatures and derivatives (shade plugin output, for instance), along with installed
and deployed copies, contain resolved values.
> We attempted this for version expressions in 2.1.0, but this had several problems, including
not being in place for plugin executions, and resolving version expressions within plugin
configurations. When we tried to remedy this in 2.2.0, a bunch of more subtle issues sprang
up, which are described in the link at the top of this description. In short, we can't really
solve this adequately in 2.2.0 without performing major surgery, and even then I'm not sure
it'd work. We need to consider this as a design requirement for Maven 3.x, where we can design
it into the system instead of trying to retrofit...
